A Texas hospital is under fire for allegedly telling a surgical patient she had to leave the hospital immediately because she was an illegal immigrant.

Maria Sanchez, 24, told the Houston Chronicle that she had been at John Sealy Hospital -- part of the University of Texas Medical system -- for six days when a doctor told her on Jan. 12 that she should go to Mexico to have surgery on her growing spinal tumor. The hospital discharged her that day, the paper reported.
